Multifunctional tobacco leaf fine selection device

Abstract

The invention provides a multifunctional tobacco leaf fine selection device. The multifunctional tobacco leaf fine selection device is characterized by comprising a tobacco leaf feeding device (1), a sorting box body (3) connected above the tail end of the feeding device (1), a negative-pressure draught fan device (4) mounted at the upper end of the sorting box body (3), a high-speed net belt conveying device (5) covering the inner part of the sorting box body (3) and a high-speed belt conveyor (6) located under the output end of the high-speed net belt conveying device (5). According to the multifunctional tobacco leaf fine selection device, tobacco leaves are thrown out from the outlet of the sorting box body (3) in a mutual clamping manner of the high-speed net belt conveying device (5) and the high-speed belt conveyor (6), so that the flat treatment on the tobacco leaves can be realized; a first air flow injection device (503) is mounted at a discharging end of the high-speed net belt conveying device, so that the tobacco leaves are prevented from being continuously stuck on a high-speed net belt and the tobacco leaves can be smoothly thrown out.

Description

technical field [0001] The invention relates to the technical field of material removal, in particular to a method and equipment for removing foreign matter and mildew of tobacco leaves and sorting low-grade tobacco leaves. Background technique [0002] In the tobacco shredded production line, threshing and redrying production line, it is the key process to ensure the quality of cigarettes to efficiently and accurately remove heavy foreign matter, light foreign matter, mildewed tobacco leaves, and low-grade tobacco leaves. Tobacco companies mostly adopt the method of winnowing for separation, and use the tobacco leaves to be suspended in the sorting box under the lifting effect of the airflow to realize the sorting of heavy foreign matter. During the sorting process, a large amount of tobacco leaves will be suspended in the sorting box, The attitude of spinning and tobacco leaves cannot be controlled, the sorting speed of tobacco leaves is low, and winnowing cannot complete ...

Problems solved by technology

[0002] In the tobacco shredded production line, threshing and redrying production line, it is the key process to ensure the quality of cigarettes to efficiently and accurately remove heavy foreign matter, light foreign matter, mildewed tobacco leaves, and low-grade tobacco leaves. Tobacco companies mostly adopt the method of winnowing for separation, and use the tobacco leaves to be suspended in the sorting box under the lifting effect of the airflow to realize the sorting of heavy foreign matter. During the sorting process, a large amount of tobacco leaves will be suspended in the sorting box, The attitude of spinning and tobacco leaves cannot be controlled, the sorting speed of tobacco leaves is low, and winnowing cannot complete the sorting of mildewed tobacco leaves and low-grade tobacco leaves, so it is necessary to use optical sorting equipment for sorting after thinning and shaping the leaves

Although the Chinese patent with the publication number CN1939164A discloses a method and equipment for removing tobacco foreign matter, due to the turbulence of the air flow in the box, the use of an air blowing device in the box has a poor effect on removing mildewed tobacco leaves and light foreign matter. It is extremely difficult to identify tobacco leaves under high-speed transport without attitude shaping, overlapping tobacco leaves, and using a single-sided imaging device, and it is impossible to achieve complete imaging recognition of tobacco leaves

Another example is that the Chinese patent disclosed by the publication number CN202893676U also has the phenomenon of tobacco leaves spinning and flying randomly in the box, and it is impossible to identify mildew and low-grade tobacco leaves.
